Title: Paint can holder
Inventor: TORODE PATRICK ARTHUR WALLY
IPC: E06C7/14
Filed: 1982-05-11
Abstract: A holder for receiving a decorators bucket on a step ladder comprises a pair of retaining arms pivotally connected together for engagement with a step ladder, one of the arms being extended on the opposite side of the pivot to form a ring for encircling the bucket and the other arm being in the form of a cradle for supporting the bucket so that when the bucket is in the cradle its weight causes the retaining arms to move together about the pivot to enhance the gripping action on the step ladder. <IMAGE>

Title: An improved electric plug assembly
Inventor: YATES VINCENT ANTHONY
IPC: H01R13/68
Filed: 1982-12-22
Abstract: In a non-rewirable electric plug assembly in which a preformed base 1 and cover 11 are permanently secured together, the live pin 3 and its associated U-shaped fuse contact 7 are mounted in the cover and the neutral pin 4, the earth pin 5 and the other fuse contact 8 and their associated terminals are mounted on the base. When the base 1 and cover 11 are assembled together, the live pin 3 passes through a hole in the base and its associated fuse contact 7 passes through holes in the base into the fuse recess 6. In the event of failure of the means permanently securing together the base 1 and cover 11, the live pin 3 and its associated fuse contact 7 will be carried by the cover when it disengages from the base. Preferably, initially, the cartridge fuse resiliently gripped by the fuse contacts and the fuse contacts will resist separation of the base and cover. Pin 3 is mounted on post 14 and strap portions 23, 24 common to the pin and fuse contact 7 are held down by integral cover members 33 and 34. <IMAGE>

Patent GB-2132832-A (GB)
Title: Supplying electrostatic spraying apparatus with high DC voltage
Inventor: PERRIN HENRI
IPC: B05B5/053
Filed: 1983-10-21
Abstract: A low voltage supply (1) provides a low DC voltage (V3) which, in the absence of current, has a value substantially higher than that of the stabilized low DC voltage (V4) normally delivered by a voltage stabilizer circuit (6) to a high voltage generator (7) when the intensity of the current is less than a threshold value. A passive circuit element (11) eg. a resistor is connected upstream of the stabilizer circuit (6) to cause the low voltage supply to the circuit to decrease progressively so that the low voltage passes, while decreasing, through a value substantially equal to the value of the stabilized low DC voltage (V4) when the intensity of the current reaches the threshold value, this latter corresponding to a normal operating distance of an electrostatic spray gun (9) from a grounded object (10) being sprayed. The resistor (11) may be omitted if a saturated core transformer is used. <IMAGE>

Patent GB-2153413-A (GB)
Title: Well tool locking apparatus
Inventor: BOGARD EDWARD L
IPC: E21B23/04
Filed: 1985-01-31
Abstract: A clamping apparatus for locking tools in a well includes a first piston 32 sealably engaging a hollow body member 20 to form a chamber 36, which is filled with a working fluid. A bias member or spring 39 moves the first piston 32, extending a clamping arm 12 connected to the first piston 32 against the well wall. A second piston 28 is sealably engaged in a bore 30 in the first piston 32; the bore 30 is in fluid communication with the chamber 36. The second piston 28 is driven into the bore 30 by a motor 22, increasing the pressure in the chamber 36 through a passage 38 in the first piston 32 between the bore 30 and the chamber 36. This increased pressure further urges the first piston 32 and locks the clamping arm 12 against the well wall. The hydraulic pressure is released, and the clamping arm 12 is unlocked, by opening a valve 46 in a line 47 between the chamber 36 and a reservoir 45. The clamping arm 12 is retracted by driving the second piston 28 into the bore 30 into contact with the first piston 32 forcing the first piston 32 back against the spring 39. <IMAGE>

Title: Method of producing a union for the flow and return pipes of panel radiators
Inventor: ISENHOFER BODO
IPC: B21D53/02
Filed: 1985-10-30
Abstract: A method is disclosed of producing a union for panel radiators, the union comprising a spherical hollow body (22, Figure 5) having a pipe connection sleeve (23) which merges into the interior of the hollow body, which body is formed, perpendicularly to such sleeve, with a connection aperture 7 for the radiator. In the method, a round (10, Figure 3) of sheet metal is shaped by deep drawing into a dished member (20) which is subsequently upset so as to comprise a spherical hollow-body part (22) merging into a neck part (23). One side of the hollow-body part is formed with a facet 5 which will subsequently be operative for the engagement of a welding electrode for press welding. The neck part (23) is formed with an internal screwthread 6, and that side of the spherical hollow-body part which is opposite the facet 5 is drilled to provide the opening 7 for connection of the radiator. No separate parts have to be produced and fitted in this method. The method uses a very small amount of material so that angle unions can be produced cheaply in large batches. <IMAGE>
